What condition is characterized by low core body temperature?

The condition characterized by low core body temperature is hypothermia. Hypothermia occurs when the body loses heat faster than it can produce it, leading to a significant drop in core body temperature, typically defined as below 95°F (35°C). This drop in temperature can impair the body's normal physiological functions and can be life-threatening if not addressed promptly.

In contrast to hypothermia, hyperthermia refers to an elevated core body temperature due to excessive heat exposure or internal heat production. Fever is a natural response to infection, resulting in an increase in body temperature that is part of the immune response. Heat exhaustion is a condition that arises from prolonged exposure to high temperatures, often accompanied by dehydration, but it does not involve a drop in core body temperature. Thus, focusing on temperature reduction helps clarify why hypothermia is the accurate choice in this context.
